Stainless Steel Tubes
We are offering stainless steel tubes. It is available in a variety of compositions, most popular of which are astm-a-213, grade td-321. (16% cr, 8%n stabilized with titanium) and astm-a-213 grade td-347 (18% cr, 8% ni) stabilized with columbium. Either of these two may be used upto to 649oc. Care must be given to choice of welding rod to avoid brittleness in the welds.
...moreSpiral Finned Tubes
We are offering spiral finned tubes. While it is not necessary to tell engineers what finned tubes are, or that their use is mandatory in cases of gas-liquid heat exchange where the film coefficient ratio is above 2, it is essential to tell the engineers that m.j.patel's finned tubes are backed by not only engineering excellence of manufacture, but also by our zealously guarded reputation for the finest quality of all our products.
...moreHeat Exchanger Tubes
We are offering heat exchanger tubes for pressure vessels and reaction vessels in m.s., al, monel, inconel, cupronickel, etc., m.j. Patel employs the latest techniques for expanding tube ends into tube sheets. High pressure tests are always carried out on these heat exchangers before they leave the factory. Brass, copper, m.s. And s.s. Tube sheets are used.
...moreErw Boiler Tubes
we are offering Erw Boiler Tubes. For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes. The electrodes are copper disks connected to the secondary of a revolving transformer assembly.
...moreBoiler Tubes
we are offering Boiler Tubes. These Tubes have very complicated shapes to allow Inspection openings and burner throats and fabrication require intricate binding on CNC programmable bending Machines and checking on 3D layouts.
...moreWater wall tubes
Water Wall Tubes: These are tubes in the Boiler where water is evaporated to steam and are also called Steam Generating Tubes. These Tubes also form the Walls of the Boiler and are hence called Water Walls or Water Wall Panels. These Tubes have very complicated shapes to allow Inspection openings and burner throats and fabrication require intricate binding on CNC programable bending Machines and checking on 3D layouts.
...morewater wall panel
we are offering Water Wall Panel. Water wall panels are used in Waste Heat recovery boilers. We can manufacture 100 MT Month of panels with required accuracy.
...moreStudded Tubes
we are offering Studded Tubes. An electric current is applied by contacts on the stud and tube and the studded coils resistance in this circuit produces the heat necessary for welding. Maximum resistance and therefore maximum heating occurs at the interface between the Stud and the tube. Pressure to forge the Stud and the tube together at the point of maximum heating is applied by various forms of tooling.
...moreSuperheater Coils
Superheater Coils: Super heater coils are used in a boiler to generate saturated steam. The super heater coils are specially used in Boilers of Power plant.
...morehelical finned tubes
We are offering helical finned tubes. (embedded fin) the g fin strip is wound into a machined groove and securely locked into place by back filling with base tube material. This ensures that maximum heat transfer is maintained at high tube metal temperatures. Maximum operating temperature for this fin type is 450°c.
